CROSS-REFERENCE TO RELATED APPLICATION

This patent application claims priority to U.S. Provisional Patent Application No. 63/007,717, filed on Apr. 9, 2020, entitled “VIDEO AWARE TRANSMISSION AND MULTIPLE INPUT MULTIPLE OUTPUT LAYER PROCESSING,” and assigned to the assignee hereof. The disclosure of the prior application is considered part of and is incorporated by reference into this patent application.

FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for video aware transmission and multiple input multiple output (MIMO) layer processing.

BACKGROUND

Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, orthogonal frequency-division multiple access (OFDMA) systems, single-carrier frequency-division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

A wireless network may include a number of base stations (BSs) that can support communication for a number of user equipment (UEs). A UE may communicate with a BS via the downlink and uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receive point (TRP), a New Radio (NR) BS, a 5G Node B, or the like.

The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate on a municipal, national, regional, and even global level. NR, which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and/or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein, one skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein.

It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.

Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

It should be noted that while aspects may be described herein using terminology commonly associated with a 5G or New Radio (NR) radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G).

FIG. 1 is a diagram illustrating an example of a wireless network 100, in accordance with the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and/or an LTE network, among other examples. The wireless network 100 may include a number of base stations 110 (shown as BS 110 a, BS 110 b, BS 110 c, and BS 110 d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UEs) and may also be referred to as an NR BS, a Node B, a gNB, a 5G node B (NB), an access point, a transmit receive point (TRP), or the like. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to a coverage area of a BS and/or a BS subsystem serving this coverage area, depending on the context in which the term is used.

A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs having association with the femto cell (e.g., UEs in a closed subscriber group (CSG)). ABS for a macro cell may be referred to as a macro BS. ABS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In the example shown in FIG. 1 , a BS 110 a may be a macro BS for a macro cell 102 a, a BS 110 b may be a pico BS for a pico cell 102 b, and a BS 110 c may be a femto BS for a femto cell 102 c. A BS may support one or multiple (e.g., three) cells. The terms “eNB”, “base station”, “NR BS”, “gNB”, “TRP”, “AP”, “node B”, “5G NB”, and “cell” may be used interchangeably herein.

In some aspects, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a mobile BS. In some aspects, the BSs may be interconnected to one another and/or to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network.

Wireless network 100 may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. In the example shown in FIG. 1 , a relay BS 110 d may communicate with macro BS 110 a and a UE 120 d in order to facilitate communication between BS 110 a and UE 120 d. A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like.

Wireless network 100 may be a heterogeneous network that includes BSs of different types, such as macro BSs, pico BSs, femto BSs, relay BSs, or the like. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in wireless network 100. For example, macro BSs may have a high transmit power level (e.g., 5 to 40 watts) whereas pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

A network controller 130 may couple to a set of BSs and may provide coordination and control for these BSs. Network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with one another, e.g., directly or indirectly via a wireless or wireline backhaul.

UEs 120 (e.g., 120 a, 120 b, 120 c) may be dispersed throughout wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, or the like. A UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, biometric sensors/devices, wearable devices (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicular component or sensor, smart meters/sensors, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium.

Some UEs may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and/or location tags, that may communicate with a base station, another device (e.g., remote device), or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband internet of things) devices. Some UEs may be considered a Customer Premises Equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as processor components and/or memory components. In some aspects, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled.

In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular RAT and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, an air interface, or the like. A frequency may also be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

In some aspects, two or more UEs 120 (e.g., shown as UE 120 a and UE 120 e) may communicate directly using one or more sidelink channels (e.g., without using a base station 110 as an intermediary to communicate with one another). For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol or a vehicle-to-infrastructure (V2I) protocol), and/or a mesh network. In this case, the UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station 110.

Devices of wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided based on frequency or wavelength into various classes, bands, channels, or the like. For example, devices of wireless network 100 may communicate using an operating band having a first frequency range (FR1), which may span from 410 MHz to 7.125 GHz, and/or may communicate using an operating band having a second frequency range (FR2), which may span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a “sub-6 GHz” band. Similarly, FR2 is often referred to as a “millimeter wave” band despite being different from the extremely high frequency (EHF) band (30 GHz-300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. Thus, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies less than 6 GHz, frequencies within FR1, and/or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies within the EHF band, frequencies within FR2, and/or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and techniques described herein are applicable to those modified frequency ranges.

As indicated above, FIG. 1 is provided as an example. Other examples may differ from what is described with regard to FIG. 1 .

FIG. 2 is a diagram illustrating an example 200 of a base station 110 in communication with a UE 120 in a wireless network 100, in accordance with the present disclosure. Base station 110 may be equipped with T antennas 234 a through 234 t, and UE 120 may be equipped with R antennas 252 a through 252 r, where in general T≥1 and R≥1.

At base station 110, a transmit processor 220 may receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS(s) selected for the UE, and provide data symbols for all UEs. Transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232 a through 232 t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232 a through 232 t may be transmitted via T antennas 234 a through 234 t, respectively.

At UE 120, antennas 252 a through 252 r may receive the downlink signals from base station 110 and/or other base stations and may provide received signals to demodulators (DEMODs) 254 a through 254 r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254 a through 254 r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller/processor 280. The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a channel quality indicator (CQI) parameter, among other examples. In some aspects, one or more components of UE 120 may be included in a housing 284.

Network controller 130 may include communication unit 294, controller/processor 290, and memory 292. Network controller 130 may include, for example, one or more devices in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

Antennas (e.g., antennas 234 a through 234 t and/or antennas 252 a through 252 r) may include, or may be included within, one or more antenna panels, antenna groups, sets of antenna elements, and/or antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include a set of coplanar antenna elements and/or a set of non-coplanar antenna elements. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include antenna elements within a single housing and/or antenna elements within multiple housings. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of FIG. 2 .

On the uplink, at UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and/or CQI) from controller/processor 280. Transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254 a through 254 r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, a modulator and a demodulator (e.g., MOD/DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulators and/or demodulators 254, MIMO detector 256, receive processor 258, transmit processor 264, and/or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller/processor 280) and memory 282 to perform aspects of any of the methods described herein, for example, as described with reference to FIGS. 3-7 .

At base station 110, the uplink signals from UE 120 and other UEs may be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller/processor 240. Base station 110 may include communication unit 244 and communicate to network controller 130 via communication unit 244. Base station 110 may include a scheduler 246 to schedule UEs 120 for downlink and/or uplink communications. In some aspects, a modulator and a demodulator (e.g., MOD/DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modulators and/or demodulators 232, MIMO detector 236, receive processor 238, transmit processor 220, and/or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller/processor 240) and memory 242 to perform aspects of any of the methods described herein, for example, as described with reference to FIGS. 3-7 .

As indicated above, FIG. 2 is provided as an example. Other examples may differ from what is described with regard to FIG. 2 .

FIG. 3 is a block diagram conceptually illustrating an example of a wireless communication network 300 in which a BS (e.g., BS 110) provides streaming video to a UE (e.g., UE 120), in accordance with various aspects of the present disclosure. As shown in FIG. 3 , wireless communication network 300 may include an Internet Protocol (IP) multimedia core network subsystem (IMS) core 305, a packet data network gateway (PGW) 310, a serving gateway (SGW) 315, a BS 110 (e.g., which may include a communication device 320), and a UE 120. As further shown in FIG. 3 , BS 110 and UE 120 may communicate via an access link (e.g., a Uu interface).

PGW 310 includes one or more devices capable of providing connectivity for UE 120 to external packet data networks (e.g., via IMS core 305). For example, PGW 310 may include one or more data processing and/or traffic transfer devices, such as a gateway, a router, a modem, a switch, a firewall, a network interface card (NIC), a hub, a bridge, a server device, an optical add-drop multiplexer (OADM), or any other type of device that processes and/or transfers traffic. In some implementations, PGW 310 may aggregate traffic received from one or more SGWs 315, and may send the aggregated traffic to IMS core 305. Additionally, or alternatively, as described in more detail herein, PGW 310 may receive traffic from IMS core 305 and may send the traffic to UE 120 via SGW 315 and BS 110. For example, PGW 310 may receive a video stream from IMS core 305 that is to be provided to BS 110 for processing and transmission to UE 120 UE 120.

SGW 315 includes one or more devices capable of routing packets. For example, SGW 315 may include one or more data processing and/or traffic transfer devices, such as a gateway, a router, a modem, a switch, a firewall, a NIC, a hub, a bridge, a server device, an OADM, or any other type of device that processes and/or transfers traffic. In some implementations, SGW 315 may aggregate traffic received from one or more BSs 110 associated with the wireless communication network 300 and may send the aggregated traffic to IMS core 305 (e.g., via PGW 310) and/or other network devices. SGW 315 may receive traffic from IMS core 305 (e.g., via PGW 310) and/or other network devices and may send the received traffic to BS 110 for processing and transmission to UE 120. For example, SGW 315 may receive real-time transport protocol (RTP) data and/or real time control transport protocol (RTCP) data with an RTP payload format H.264 (e.g., RTP data conveying the streaming video via general packet radio service (GPRS) tunneling protocol (GTP)). In this case, SGW 315 may provide the RTP data and/or RTCP data (e.g., the streaming video) to BS 110 via GTP and RTP and/or RTCP.

In some communications systems, such as Video Over 5G/NR (VoNR) or Video Over LTE (ViLTE), a BS and a UE may communicate using full duplex voice with either simplex or full duplex video streaming. The BS and UE may enable a relatively high level of synchronization between the voice and video streaming (which may be referred to, collectively, as streaming content), thereby enabling video-calling, streaming entertainment, and/or the like. The BS may activate dedicated bearers for transport of video and audio RTP traffic. The BS may assign different quality of service (QoS) levels for video (e.g., QoS class identifier (QCI) 2 for video) and audio (e.g., QCI 1 for audio), thereby providing some differentiation in reliability. For example, in this case, the BS prioritizes streaming audio, which may be delay and jitter sensitive, over streaming video, which may be less delay or jitter sensitive. In other words, during a video-conference use case, a brief interruption to audio from a speaker may be more disruptive to the video-conference than a brief interruption to video of the speaker.

However, at a medium access control (MAC) layer or physical (PHY) layer, the BS may perform procedures, such as scheduling, coding, modulation, multiplexing, orthogonal frequency division multiplexing (OFDM) symbol generation, and/or the like, agnostic of data that is being processed. In other words, the BS may process all data of a video stream without regard to what part of the video stream the data represents. As a result, interruptions to data transmission may result in excessively large effects to quality of experience (QoE) when the interruption affects a part of a video stream that has a large QoE effect.

Some aspects described herein provide video aware processing for streaming video. For example, as described below, a communication device (e.g., a BS or a component of a BS) may classify portions of streaming video based at least in part on an effect of each portion on QoE for the streaming video and may provide differential protection to portions based at least in part on the classification. In other words, the communication device may assign different portions of streaming video to different code blocks and/or transport blocks based at least in part on the classification. For example, the communication device may generate a first data stream for header data (e.g., RTP, user datagram protocol (UDP), IP header data) (a lack of which may have a first effect on QoE), a second data stream for transparent operation (a lack of which may have a second effect on QoE), a third data stream for a first QoS classification (a lack of which may have a third effect on QoE), a fourth data stream for a second QoS classification (a lack of which may have a fourth effect on QoE), and/or the like.

In this case, the communication device may provide differential protection to the different code blocks and/or transport blocks associated with different data streams by mapping the different code blocks and/or transport blocks (e.g., the data streams composed thereof) to different multiple input multiple output (MIMO) layers to provide differential reliability. In some aspects, each MIMO layer may have a different signal to noise ratio (SNR) and the communication device may assign different data streams to different MIMO layers based at least in part on the different SNRs to achieve differential reliability. In this way, the communication device ensures higher reliability for data associated with providing a high level of QoE relative to non-video-aware processing, thereby increasing QoE of streaming video. In other words, the communication device may provide relatively higher protection to code blocks and/or transport blocks conveying data from data streams with a higher effect on QoE and relatively lower protection to code blocks and/or transport blocks conveying data from data streams with a lower effect on QoE. In this way, the communication device ensures that data with a greatest effect on QoE (e.g., a greatest likelihood of interrupting consumption of the streaming video) is least likely to be dropped rather than all data having an approximately equal or randomly distributed likelihood of being dropped as may occur in non-video-aware processing. Although some aspects are described herein in terms of streaming video, other types of streaming content are contemplated.

Communication device 320 may include BS 110 or be a component of BS 110. For example, communication device 320 may be a video processing component that includes one or more of controller/processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and/or the like of BS 110. As shown in FIG. 3 , BS 110 may decompose and/or transcode received packets (e.g., packets received from SGW 315) to identify underlying aspects of the data, such as different aspects of the streaming video (e.g., different video aspects, different audio aspects, and/or the like), as described in more detail herein. In this case, based on received RTP data (e.g., RTP H.264 payload data), communication device 320 may assign portions of the received data to different code blocks and/or transport blocks, map the different code blocks and/or transport blocks to different MIMO layers, and provide a set of data radio bearers (DRBs) based at least in part on the mapping. In this case, BS 110 may provide the video aware DRBs and RTCP output data over the Uu interface to UE 120.

UE 120 may receive the video aware DRBs and the RTCP output data via the Uu interface. UE 120 may reconstruct the underlying RTP data (e.g., the RTP H.264 payload data) and process the underlying RTP data using a video decoder (e.g., an RTP H.264 decoder) to obtain a decoded video stream.

As indicated above, FIG. 3 is provided as an example. Other examples may differ from what is described with respect to FIG. 3 .

FIGS. 4A and 4B are diagrams illustrating examples 400/400′ of data processing by a communication device to enable a BS to provide streaming video to a UE, in accordance with various aspects of the present disclosure.

As shown in FIG. 4A, a communication device (e.g., BS 110, communication device 320) may decompose streaming content (e.g., streaming video) into a plurality of portions associated with different characteristics to enable providing video aware DRBs. For example, the communication device may classify portions of the streaming content into an intra-code picture (I-frame) category (e.g., a frame which may include an entire image that is coded without reference to any other frame, but which may include references to portions of the frame itself), a predicted picture (P-frame) category (e.g., a frame which may include image data and motion vector displacements, and may reference previous frames in a decoding order), or a bidirectional predicted picture (B-frame) category (e.g., a frame which may include image data and/or motion vector displacements and may be decodable based at least in part on prior decoding of a subsequent frame that is to be displaced). These are simply examples of categories that may be used. In practice, the communication device may classify the streaming content according to one or more other types of heuristics. The communication device may assign different portions of the streaming content to different DRBs for processing (e.g., for transport block cyclic redundancy check (CRC) attachment, code block segmentation, channel coding, rate matching, code block concatenation, and/or the like, as described in more detail herein).

In some aspects, the communication device may map transport blocks to MIMO layers based at least in part on a classification of the streaming content. For example, based at least in part on classifying a first portion of the streaming content as having a relatively large effect on a quality of experience (QoE) (e.g., an absence of the first portion of the streaming content reduces a usability of the streaming content more than an absence of other portions, such as by preventing a playback device from playing any of the streaming content, which may affect QoE more than, for example, a second portion of the streaming content that is associated with maintaining exact synchronization between a video and audio of the streaming content, without which playback may still continue with, for example, poor synchronization), the communication device may map a DRB including transport blocks of the first portion of the streaming content to MIMO layers with higher signal to noise ratio (SNR) values (e.g., providing a greater level of reliability relative to other MIMO layers). In contrast, the communication device may map a DRB including a second portion of the streaming content that has a relatively low effect on QoE to a MIMO layer with a lower SNR value (e.g., providing a lower level of reliability relative to other MIMO layers). In this way, the communication device provides video aware processing of DRBs to enable greater quality of service (QoS) for DRBs with higher levels of effect on QoE, thereby providing greater QoE at a UE 120 that is to receive streaming content.

As further shown in FIG. 4A, based at least in part on processing the plurality of DRBs, the communication device may multiplex the plurality of DRBs, modulate a multiplexed stream, perform resource mapping, and perform orthogonal frequency division (OFDM) symbol generation to enable transmission of the plurality of DRBs with differential protection.

Similarly, as shown in FIG. 4B, the communication device may assign different classifications of the streaming content to different code blocks. For example, the communication device may assign I-frames to a first code block, P-frames to a second code block, B-frames to a third code block, and/or the like. Additionally, or alternatively, the communication device may classify portions of the streaming content based at least in part on other contemplated heuristics and assign different classifications to different code blocks of a physical layer transport block. In this case, the communication device may map the different code blocks to different MIMO layers based at least in part on an effect of content assigned to each code block on QoE of the streaming content and based at least in part on SNRs of the different MIMO layers. For example, the communication device may map a code block with high-QoE effect portions of the streaming content to a high SNR MIMO layer and a code block with low-QoE effect portions of the streaming content to a low SNR MIMO layer. In this way, the communication device enables video-aware processing to provide improved QoS to high-QoE code blocks, thereby providing higher QoE at a receiver device, such as UE 120.

As indicated above, FIGS. 4A and 4B is provided as examples. Other examples may differ from what is described with respect to FIGS. 4A and 4B.

FIGS. 5A and 5B are diagrams illustrating examples 500/500′ of block production by a communication device to enable a BS to provide streaming video to a UE, in accordance with various aspects of the present disclosure.

As shown in FIG. 5A, a medium access control (MAC) entity of a communication device may generate a transport block (e.g., based at least in part on service data adaptation protocol (SDAP) block generation, packet data convergence protocol (PDCP) block generation, and radio link control (RLC) block generation). For example, the MAC entity may concatenate two RLC protocol data units (PDUs) from a first radio bearer (RB_(x)) and one RLC PDU from a second radio bearer (RB_(y)). After concatenation, the communication device may add cyclic redundancy check (CRC) bits and divide a transport block into a plurality of code blocks. In this case, code block 2, for example, includes data of the first radio bearer and data of the second radio bearer. As a result, based at least in part on data from a plurality of DRBs being multiplexed into a common code block, the MAC entity provides the same QoS (e.g., the QoS of the common code block) for each radio bearer.

In contrast, as shown in FIG. 5B, a communication device (e.g., BS 110, communication device 320, and/or the like) may include a MAC entity that may determine a code block size. In this case, based at least in part on determining the code block size, the MAC entity of the communication device may allocate RLC PDUs to code block size units, such that different code blocks may be mapped to obtain different QoS, as described above. For example, as shown, the first code block includes only data from the first radio bearer and the second code block includes only data from the second radio bearer. In this case, the communication device may include padding bits to enable data of a radio bearer to fill an entire code block. In this way, based at least in part on ensuring that each radio bearer is in a separate code block from each other radio bearer, the communication device enables QoE based video-aware processing without changing a layer 1 (L1) block production procedure.

As indicated above, FIGS. 5A and 5B is provided as an example. Other examples may differ from what is described with respect to FIGS. 5A and 5B.

FIG. 6 is a diagram illustrating an example process 600 performed, for example, by a communication device, in accordance with various aspects of the present disclosure.

As shown in FIG. 6 , in some aspects, process 600 may include classifying a set of packets of streaming video content based at least in part on one or more video characteristics, wherein the one or more video characteristics relate to an effect of a packet on a quality of experience of providing the streaming video content (block 610). For example, the communication device (e.g., using controller/processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and/or the like) may classify a set of packets of streaming video content based at least in part on one or more video characteristics, as described above.

For example, the communication device (e.g., using controller/processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and/or the like) may assign the set of packets to a plurality of transport blocks based at least in part on classifying the set of packets, as described above.

In a fourth aspect, alone or in combination with one or more of the first through third aspects, assigning the set of packets to the plurality of transport blocks includes assigning a first one or more packets to a first data stream with a first quality of service and a second one or more packets to a second data stream with a second quality of service.

Although FIG. 6 shows example blocks of process 600, in some aspects, process 600 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in FIG. 6 . Additionally, or alternatively, two or more of the blocks of process 600 may be performed in parallel.
